Using the ZigZag Density Tumbler In (and Out) of the Classroom


by Linda Dunnavant

The ZigZag Density Tumbler is an elegant desk “toy” and much more.  Turn the tumbler over and watch two different colors of droplets float down in a relaxing zigzag pattern.  I like to keep mine on my desk.  I often pick it up and watch it while I clear my head.  Not only is the tumbler a soothing, relaxing activity for busy adults, but it also provides so many possibilities for calming, inspiring, and teaching students.

Engaging Students with Electrochemistry… and Goldenrod Paper


Educational Innovations Blogby Nancy Foote

I’m in love with goldenrod paper.  I’ve loved it for a long time.  In my never-ending quest to emotionally entangle my students in the content of our science curriculum, Color-Changing Goldenrod Paper provides a long-lasting entanglement.

The Chemistry of Currency


Dr. Kenneth Lyle, Duke University Department of Chemistryby Gabrielle Hodgins and Dr. Kenneth Lyle, Duke University, Durham NC

The wonders of magnetic ink!

INTRODUCTION

Demonstrating the magnetic ink used in printing US currency has proven to engage audiences of all ages because of its relevance to everyday life.  Nearly everyone has used machines that distribute and/or accept currency but few understand how the machines distinguish between the various denominations.  The key is in the face of each denomination.  Magnetic ink is used in the printing of the currency.  Each denomination has a different face and, therefore, a different magnetic signature.  Similar to a bar code reader, the machines recognize the denomination by its magnetic signature.  A strong magnet, such as a neodymium magnet, can be used to demonstrate the magnetic character of US currency.
